  2. 1. On Reconfigurable MEMS Antennas and Coupling Matrix Estimation

    Author : Marc Mowlér; Björn Lindmark; Björn Ottersten; Pertti Vainikainen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; Antennas; Estimation Theory; Telecommunication; Telekommunikation;

    Abstract : In this thesis, two different topics are treated related to wireless communication. Part I presents three different reconfigurable MEMS integrated antennas for MIMO applications. Simulation and measurement results are presented along with brief discussions on the topic of antenna selection with reconfigurable antenna elements. READ MORE

  4. 2. Analysis and Design of Base Station Antennas for Mobile Communications

    Author : Björn Lindmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization diversity; dual polarization; adaptive antennas; moment method; genetic algorithm; antenna arrays; radio propagation; channel sounding; aperture coupled patch;

    Abstract : The thesis deals with base station antennas and the environment they work in. Polarization diversity, dual band operation, and adaptive antenna systems are discussed with emphasis on how antennas for these applications should be designed. We compare the polarization diversity performance of different types of dual polarized antenna elements. READ MORE

  6. 4. Bridging the gap between clinical trials and clinical practice : sacubitril-valsartan in heart failure as a model

    Author : Helena Norberg; Krister Lindmark; Ellinor Bergdahl; Eva-Lotta Glader; Björn Wettermark; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systematic implementation; healthcare quality improvement; chronic disease management; heart failure; sacubitril-valsartan; real-world population; sex differences; kardiologi; Cardiology;

    Abstract : When novel treatments prove more effective than standard therapies, a swift and effective implementation is needed to reach cost-effectiveness and to benefit eligible patients. Meanwhile, women and elderly are often under-represented in clinical trials, which creates a knowledge gap on how to optimize treatment in clinical practice. READ MORE

  7. 5. Amoebae as Hosts and Vectors for Spread of Campylobacter jejuni

    Author : Jenny Olofsson; Patrik Ellström; Björn Olsen; Diana Axelsson-Olsson; Hans Lindmark; Uppsala universitet; []
    Keywords : Amoebae-Bacteria interactions; Campylobacter jejuni; epidemiology; environmental stress; low pH; Acanthamoeba; coculture; intracellular trafficking; bacterial survival; beverages; ACC-method; enrichment; genetic stability; Trojan horse; reservoir; host; vector; Infektionssjukdomar; Infectious Diseases;

    Abstract : Campylobacter jejuni is the leading bacterial cause of gastrointestinal diarrheal disease in humans worldwide. This zoonotic pathogen has a complex epidemiology due to its presence in many different host organisms. READ MORE
